Prostanoid Receptors

Prostanoid receptor agonists and antagonists act on the G protein-coupled receptors for prostaglandins and thromboxane. Prostanoids are lipid mediators formed from arachidonic acid by cyclooxygenase enzymes. Under the 1994 classification by the International Union of Pharmacology (IUPHAR), each receptor is named after its preferred natural ligand. The receptors for prostaglandin D2 (DP), E2 (EP), F2α (FP), prostacyclin (IP) and thromboxane A2 (TP) follow this scheme. Prostaglandin E2 (PGE2) acts on four subtypes, EP1 to EP4, which couple to different G proteins. Natural agonists in this category include PGE2 and dinoprost, also called prostaglandin F2α. Antagonists include laropiprant at the DP1 receptor, ONO-AE3-208 at EP4 and CAY10471 Racemate at DP2, the second receptor for prostaglandin D2.
